To [bZZ 'LI/hum it may concern:

Be it known that I, GEORGE OBERBECK, a citizengofthe United States,residing atNew York, county of New York, State of New York, haveinvented a new and useful Improvement in Pencil-Sharpeners, of which thefollowing is a specification.

This invention has to do with the means for permitting the operator toconveniently hold the sharpener when in use and to steady and center thepencil. Its object is to furnish a cheap and effective device for thispurpose susceptible of application and use in connectionwith theordinary hand pencil-sharpener, and it can best be explained andunderstood by reference to the accompanying drawings, in whichm Figure 1is a perspective view of a pencilsharpener provided with my improveddevice. Fig. 2 is a cross-section of the same on line 2 2, Fig. 1. Figs.3 and 4 are views ofa modification. Fig. 3 is a view of the developedblank, and Fig. 4 is a view of the completed device made from the blank.

A is the pencil-sharpener of usual construction. Upon the cylindricalportion of the body of the sharpener (which is at the end of thesharpener entered by the pencil) is mounted and secured my improveddevice. This device is made from a sheet-metal blank, which is cut out,bent, and fashioned to form the tubular portion a, which fits snuglyaround and is suitably secured to the cylindrical portion of thesharpener-body, the handle b consisting of the two extremities of theblank which are brought and fastened together flatwise, so as to formafin-like handle which projects radially from and longitudinally of the ibody of the sharpener, and the spring-yielding centering portionconsisting of strips or arms c, projecting in advance of the mouth ofthe sharpener, so that the pencil must pass between them before enteringthe sharpener. These arms or strips sustain the pencil in position,center it, and prevent it from lateral wabbling, and they aresprmg-yielding, so as to adapt themselves to the varying sizes ofpencils. The tubular portion a is secured to the sharpener in thisinstance by punching it into the body of the sharpener, as indicated atd. The two end portions which form the handle I) may be secured togetherby suitable means. In Figs. 1 and 2 a rivet e is used for the purpose.In Figs. 3 and 4 one end 4portion of the blank is formed with a tonguef, which when the blank is bent up and fashioned into the shape of thecompleted device is lapped over and upon the adj acent end portionthrough an opening formed for that purpose in the latter, as indicatedin Fig. 4.

Having described :my invention, I claim- A pencil-sharpener providedwith a holding and centering device consisting of a sheetmetal blankwhose central portion is fashioned to form the tubular portion a and thespring-yielding centering portion c, and whose ends are brought andsecured flatwise together to form the handle b, as and for the purposeshereinbefore set forth.

In testimony whereof I affiX my signature in presence of two witnesses.

GEORGE OBERBECK.
